Rectangular copper wire has specific requirements for the R-angle size. It is a special-shaped enamelled wire extended from flat wire, composed of a rectangular conductor (copper, copper alloy, and other materials) and an insulating coat. A bonding coat can also be compounded on the surface of the insulating coat to achieve self-adhesive effect.
The R-angle size of flat wires is typically half of the thickness, while rectangular wires can be manufactured with smaller R-angle sizes according to specific application requirements. This requires more precise workmanship and presents greater production challenges compared to flat wire.
Features
Compared with traditional round wires, rectangular wires provide larger surface area and superior heat dissipation performance when cross-sectional area is identical
Rectangular wires offer significant advantage in copper space factor. Under the same space constraints, compared with round and flat wires, rectangular wire achieves the highest copper space factor due to their smaller R angle advantage
Compared with round wires, rectangular wires can reduce wire DCR by 15–20%, significantly improving the electrical performance of coils
Applications
Consumer electronics
New energy vehicles
Digital electronics
Wireless charging
Aerospace
Medical equipment and other fields
Frequently Asked Questions
Can you customize the wire size and construction?
Yes. Customized conductor size, strand counts, bonding layers, and spool packaging are available.
What conductor materials and coating can you offer?
Our regular conductor materials include copper, copper alloy, aluminum, copper-clad aluminum, etc. We can supply most domestic insulation varnish and top varnish, as well as special varnish to meet unique requirements.
What information is required for a quotation?
To provide an accurate quotation, please share the wire dimensions, insulation type, thermal class, required quantity, packaging requirements, and destination country.
Is soldering required to remove enamel?
UEW enamel typically supports direct soldering under appropriate temperature conditions, depending on process requirements.
If the MOQ is not met, can it still be produced?
If the order quantity does not meet the MOQ requirement, we can still produce it for you, but the price will be higher than the MOQ price. Generally, it is calculated based on 3-5 times the MOQ unit price multiplied by the order quantity that you need, plus a startup/module fee of 1,500 RMB. (If the total price of samples is higher than the MOQ price, then we will follow the total price of MOQ)
